IMPROVEMENT IN ANTI-FRICTION BEARINGS.

Specification forming part of Letters Patent No. 131,162, dated September 10, 1872.

act description, reference being had to the accompanying drawing forming a part of this specification, in which My invent-ion relates to certain combination of devices, the object of which is to prevent any rubbing-friction of journals against their bearings. The first part of my invention relates to the construction of a circular box for the journal, with recesses in its interior periphery, incombination with a sleeve upon the shaft in such a manner that when a series of rollers is placed between the sleeves and the box to furnish a rolling bearing, the journals of such rollers may be connected by rings one to another, and such rings have room to revolve between the recessed portion of the box and the surface of the shaft without touchin g either. The second part of my invention relatesto the construction of such rollers, with two recesses upon each journal of such rollers to confine each ring to its own proper position, and further to the arrangement of such rings in such a manner that two of them shall hold each journal of each roller against lateral motion in opposite directions, so that the rollers may never touch each other while they roll and bear between the sleeve and the box.

In the accompanying drawing, Figure 1 is an end view of a journal-box embracing my improvements, and Fig. 2 is a longitudinal central section thereof.

A is the journal; B, the box; 0, the rollers; E, the sleeve; 2' i, the journals of the rollers (3; s s, the recesses or depressions in the journals of the rollers for the rings. The journals of the rollers may be formed at their 1ongitudinal centers, and the sleeve and box recessed correspondingly, in order to furnish room for the action of the rings. The journals of the rollers should be made as small as possible consistent with theirhavin g sufficient strength, in order that the rings d d may not have to be inconveniently large in order to embrace them. In order to provide space for the rings the inner periphery of the box is cut away, as shown, and the sleeve which sustains the bodies of the rollers is made so short that the peripheries of the rings extend in the direction of the center of the shaft beyond its ends without touching them or the shaft itself. Thus the rings merely serve to confine the rollers to an invariable equidistance from each other, and touch nothing but their journals. At F is shown how the box is cut away or recessed. The sleeve E may be either made separately and fastened upon. the shaft A, or the two may be in one solid piece.

The operation is obvious. When the shaft is revolved it rolls upon the rollers while the journals of the latter roll upon the inner peripheries of therin gs, and no rubbing or abrading friction takes place.

Claims.

0 having the journals i c' provided with the recesses or depressions s s, with the series of rings (1 d arranged as described, substantially in the manner and for the purpose set forth. ALMON HALL.
